My invention relates to fliers of the type used with spinning machines, and more particularly to a flier block arrangement havingimproved means for attaching and supporting the flier wires.

In Patent 2,187,862, issued to me January 23, 1940, there is disclosed a flier construction having a flier wire support member in the form of a plate adapted to fitover the head portion of the flier body or block, the plates being attached to the flier body by means of a cap positioned below the plate and attached thereto by spot weldmg.

The present invention relates to a flier of the type disclosed in the aforementioned patent and particularly to an improved form of flier wire support member, together with means for attaching the support to the flier block. After considerable experimentation, I have found that the construction of my prior patent can be substantially simplified to provide improved operation with economies in manufacture.

An object of my invention is to provide a flier block having improved means for attaching and supporting the flier wires thereon.

Another object of my invention is to provide a flier construction having means whereby the arms of the flier wires are supported in a fixed plane in the vicinity of their points of attachment to the flier block.

Yet another object of my invention is to provide an improved flier construction wherein the flier Wires are attached to the flier block by twisting or overlapping the arms thereof, portions of the arms beyond the-points of attachment being supported in a fixed plane whereby undesirable flexing of the flier wiresabout their points of support is prevented.

Still another object of my invention is to provide an improved flier wire support having means associated therewith adapted for engagement with the body of the block whereby relative movement of the support with respect to the body of the flier is prevented.

A further object of myinvention is to provide an improved flier arrangement consisting of but few parts, strong and sturdy in construction, and not liable to get out of order even after long i and continued use.

With these and other objects'in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement,

.conventional winding machine.

without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly .,understood, I have shown in the accompanying drawings means for carrying the same into prac tical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation,

- have been made the subject of illustration.

Fig. 6 is a sectional view along line 66 of Fig. 5.

Fig. 7 is an expanded perspective view.of the parts of the flier block shown in Fig. 5;"

Fig. 8 is a plan view of another modified form of flier.

Fig. 9 is a plan view of the bottom of the flier shown in Fig. 8. l

Fig. 10 is anexpanded perspective view of the parts of the-flier block shown in Fig. 8, and,

Fig. 11 is an expanded View of a modification of the flier shown in Fig. 10.

The improved construction of the present invention comprises essentially a flier block formed with a peripheral flange and a peripheral groove above and adjacent the flange, a bi-partite flier wire support member in the form of complementary sections having semi-circular shaped .cutout portions adapted to seat in the peripheral groove at opposite sides of the block. The arms,- defined by the cut-out portions, are adapted to overlap, that is to say, the" opposite arms of the complementary sections overlap when the recessed portions are seated in the peripheral groove. The complementary sections are also" provided with means adapted for engagement with the peripheral flange whereby the sections aresecurely clamped or locked to the flier body.

Referring to the drawings, and more particularly to Figure '1, there is shown a flier arrangement associated with a'bobbin I, mounted in operative position on a suitable spindle 2, of a The bobbin is provided with a head member 3, and a centrally recessed portion 4 adapted to receive aferrule.

5 having an aperture 6 through which the flier foot is inserted. The flier block, designated generally by numeral 1, comprises a centrally apertured body portion 8 having a base portion 9 and a head portion l0. Between the base and head portions, there is provided a peripheral flange ll adapted to form a seat for portions of a flier wire support member, as will be explained more fully hereinafter.

The flier block 1, reference being had to Fig. 4, is also provided with a peripheral groove 12 above and adjacent the flange II, the flange being cut away at diametrically opposite points to form slots l3 in the periphery thereof. A bipartite flier wire support member, adapted to be mounted on the flier block, is formed of complementary sections, designated generally by nueral l4, each section comprising a body portion I 5 having a semi-circular shaped recess IB cut therein, the recessed portion defining arms I! and IT. The end of the body portion opposite the recess is turned back upon itself and crimped to form slots or grooves l8 adapted to receive the arms I9, of the flier wires, as shown in Fig. 2.

It will be noted that the ends 20 of the turned over portion of the body in which slots [8 are formed are bent downwardly in overhanging relationship with the body portion of the plate so that the wires are prevented from accidental displacement out of the slots. Each section of the flier wire support member is also provided with a prong or other projection 2| adapted to seat in one of the slots I 3 formed in the peripheral flange ll of the flier wire. The purpose of this arrangement is to prevent relative movement of the flier wire support with respect to the block, that is to say, to prevent rotative movement of the plate with respect to the block.

In assembling the flier, one of the members [4 is inserted in a portion of the peripheral groove l2, with prong member 2| seated in one of the slots 3. The complementary section I4 is then inserted in the groove I2 at the opposite side of the block with prong 2| seated in the corresponding slot l3, the opposite arms l1 and I1 overlapping at the sides of the block, as more clearly shown in Fig. 2.

After the sections have been placed in the operative position, as above described, the overlapping portions may then be fastened together, as by spot welding, indicated generally by numeral 22. After the flier wire support plate has been attached to the flier body, the wires are mounted thereon by inserting an arm I 9 of one of the wires in a slot l8, the central block engaging portion 23 of the flier Wire being in engagement with the upper peripheral surface of the body of the block, the opposite arm IQ of the same wire being then inserted in slot l8 on the same side of the block. The second wire is introduced in the manner above described, the wires overlapping at points 24 on opposite sides of the block.

By means of the construction and arrangement of the flier wire supporting plate, together with the improved flier block, the supporting plate can be easily and quickly applied to the block and after it is placed in the operative position,

the flier wires about their points of support is prevented.

Referring to Figs. 5, 6 and '7, there is shown a modified form of flier construction wherein the plate is locked against rotative movement by means of the arrangement of the arm members, which are adapted for engagement with the peripheral surface of the flange II. In this arrangement, the peripheral flange is formed with flat surfaces 25 on either side thereof, and arms I! of the respective complementary sections are bent out of the normal plane of each of the base members l5 so that when the sections are inserted in the peripheral groove l2, arms I! contact with the flat surface, as more clearly shown in Fig. 6. The complementary sections are welded together as by spot welding and the wire attaching means, namely, slots l8, are the same as those described in connection with the arrangement of Fig. 1.

Referring to Figs. 8, 9, and 10, there is shown another modification of the flier construction wherein the flier wire support member is attached to the block with the overlapped portions at the ends of the plate. In this arrangement, sections 26 and 27 are provided with semi-circular recessed portions adapted to fit into the peripheral groove l2 on opposite sides of the block. The

ends 28 of section 26 are bent or crimped to form flier wire receiving slots with arms 29 of the section 27. It will be noted that section 21 is formed with prong members 30' adapted to contact with flat surfaces 3| formed on opposite sides of the block I. In assembling the flier wire support, sections 26 and 21 are inserted in the groove 12, with arms 28 and 29 in overlapping relationship, prongs 30 resting against the flat surfaces 3!. The overlapped portions are fastened together by means of spot welding as indicated by numeral 32, Fig. 9.

Referring to Fig. 11, there is shown a modification of the supporting plate arrangement disclosed in Fig. 10. In the modified form of the device, the peripheral flange H of the flier block 1 is formed with a slot 33 adapted to receive prong member 34 formed on section 35 of the plate. This section is provided with arms 36 adapted to engage with arms 3'! formed on section 38, arms 31 overlapping the arms 36 when the sections are in seated position in the peripheral groove 12.

It will be noted in connection with the arrangement of the modified form of flier construction that the complementary sections are arranged to seat in the peripheral groove and that the wire receiving slots 28 are formed by crimping the free ends of the arms formed on one of the sections. As shown in Fig. 9, the under arm at the overlap is spot welded at the bottom of the plate.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.
